我制作hubot-slack只是为了好玩。

我想要实现的事情是让hubot一次得到几个问题。例如，如下所示：

user : @hubot: add job 
hubot : what is your job ? 
user : jobless 
hubot : where is your workplace ? 
user : home 
hubot : your job has registered.

如您所见，用户只会使用 command 触发一次事件add job。所以以下是我处理它的javascript源代码。

调用部分：

robot.respond(/register me/igm, function(msg){
    //var promptConsole = new Prompt(msg);
    var questions = [
        {'question' : 'What is your name ?', 'dataname' : 'name'}
        , {'question' : 'What is your job ?', 'dataname' : 'job'}
    ];
    var promptConsole = new Prompt(msg, questions);
    promptConsole.init().startPrompt(robot);
});

和提示对象：

var Prompt = function (msg, questions) {

    console.log(msg);
    this.msg = msg;
    this.user = msg.message.user;
    this.room = msg.message.room;
    this.results;
    this.questions = questions;

    //console.log(user +' is in room [ ' + room + ' ] ');

    this.init = function () {
        this.results = [];
        for(var i = 0; i < questions.length; i ++) {
            var singleQuestion = questions[i];
            var result = {'key': '', 'question' : '', 'value' : ''};
            result.key = singleQuestion.dataname;
            result.question = singleQuestion.question;
            this.results.push(result);
        }
        return this;
    }

    this.startPrompt = function () {
        for(var i = 0; i < this.results.length; i ++) {
            console.log(this.results[i]);
            this.msg.send(this.results[i].question);
        }
    }
}

然而，这个功能不能用robot.hearor来实现robot.respond，因为用户输入只发生一次。

还有其他方法可以实现吗？如果没有，我应该将此功能分成许多部分，例如add job,add workplace等等。
